MACHINE FOR MAKING srnvns.

G. MAnTiN, and a resident of Parkersburg, in the county of -Wood Be it known that I, THOMAS est Virginia, have invented certain Improvements in Machines for Makr ing Staves, of whichv the following is a specification.

My invention is an improvement in stave machines, andhas for its object, the provision in a machine of the character specified, of new and improved means for cutting and equalizing staves, while the staves are being moved continuously through the machine.

In the drawings: Figure .1 is a perspective view of the improvement; Fig. 2 is an endview; Fig. 3 is a. transverse vertical section; and, Fig. 4 is an enlarged detail view of one of the blades.

the present embodiment of the invention, a frame 1 is provided, having lateral perforated lugs 2, for-receiving bolts or the like, to hold plate 3, is arranged transversely o the frame, at each end, and a shaft 4 is journaled longitudinally of the frame, at each side, in the extended ends of the plates. A sprocket wheel 5 is secured to each end of each shaft, adjacent to the plate, and chains 6 are arranged transversely of the frame, near each plate, running on the wheels 5. A gear wheel 7 is secured to one of the shafts 4, the said shaft being extended beyohd the frame at one end to receive the gear wheel. The pinion 8 on a shaft 9, journaled in bearings 10 on the fra1i1e, and the said shaft 9 is provided witha ulley 1 1, for receiving a belt, (not shownl chine. The shaft 9 is heldfrom longitudinal movement in the bearings, by means of the pinion 8, and a collar 12, secured to the end of the shaft by-a set screw 13.

A shaft 14 is journaled in sectional bearings 15, on a swinging frame'14 hinged at one side edge to the main frame as shown at 62. The said shaft is provided with a pulley 16 near one end, and with a friction disk 17 at its center, the said disk having oppositely arranged bevel faces 18 and 19. The shaft is also provided with collars 20 near each end to hold it from longitudinal movement, and the collars are held in place byeet screws 21.

shaft 22 is journaled on each side of Specification of Letters Patent.

disk 17, and in inclined ings 23 on the frame. he upper end of each shaft 22 extends outside of the frame, and is provided with a circular saw 24, and the inner and lower end of each shaft is provided .Witha friction disk 25, which engages the adjacent face of disk 17. The upper and outer end of each shaft' 22 is .nuts27 aid 26 on the A curved guard plate '28 each chain, each end of ofl'set laterally outward, and provided with a longitudinal slot 29, which is engaged by'a bolt 30 on the frame. By loosening the. bolts, the plates may be adjusted with respect to the chains.

A shaft 31 is arranged parallel with the shaft 14, below the/free end of the swinging frame 14", the said shaft 31 being journaled on the adjacent uprights of the frame. Sleeves 39 are arranged on the shaft near each end of tie swinging frame 14, each SltXWe being bv washers and threaded portion. is arranged above the frame to the floor. A uide h 1d e In place by a set screw 40 and having a radial arm 41, whose free end is connected to theadjacent corner of the frame 14, by means of a hanger plate 43. One end of each hanger plate ising frame as shown at 44 and the other end is pivoted to the arm as shown at 42. A sleeve 32 is arranged on shaft 31, each sleeve being held in place by a set screw 33 and being provided with a radial lug 34, having a vertical opening 35. A rod 36 is passed through theopening of each lug and a spring 37 encircles the rod between the lower face of the lug and a nut 38, threaded on to the lower 'end of the rod. The upper end of each rod 36 is flattened as shown at 45 and is secured to a bar 47 by means of a bolt 46. The bars 47 extend upwardly outside the frame, and the upper end of each bar is arched over and downwardly at 48, and a gage or guide plate 49 is supported by the portions 48 of each bar.

he plates are connected to the bar near one end of the plates, of the plates are connected by a rod 50. The lower edges of the plates 49 are spaced above the chains, and each chain passes over an inwardly extending ledge or rim 3? on the adjacent plate 3, below the plates 49. The upper run of the chain is thus held strai ht to support the staves at this point in their travel. The bars 47 are movable vertically, and each bar is guided by means and the saw is held in place position, in bear- I and the other ends wheel 17 I tion between th or guideway 60 The ends of staves,

of a pair of rollers 52. The said rollers are journaled on the frame on of the bar and each roller has .flange 53 on its outer end which over-hes the face of the bar. .The plates 49 may yield upwardly to relieve undue strain, an he said plates may yield a certain distance frame 14.

the spring 37 can no or this strain, the is lifted together with the friction whee 7. so ed, the into contact compensate swinging frame'14 the shaft 14 and Whenever'the plates 49 are is moved more firmly 25, thus increasing the frice wheel and the disks The 24 are adjacent to the upper-edges of the plates 49, and the cutting lane of the saws is inclined with respect to the lane of.the staves,

to bevel the ends thereo ,a's they are carrled past the saws by the chains 6.

Each chain 6 is provided at spaced intervals with lugs 54 (Fig. 3), each lug having its front face perpe d1cular to the top of the frame, an the rear face inclined. The lugs of the chains register, and each stave is engaged near each end by a lug, and carrie past the saws.

A cutter in one end pointed held by a h saw. "Eac bracket is provided with feet 58, held to the frame by screws or bolts 59, and each bracket is provided with a vertical groove The shank 55 fits 1n the guideway, and is held in place by means 0 screws 6, threaded into the bracket on each side of the guideway, and overlappingthe shank. B loosening the screws, the blad may be a justed vertically, and when the clamped screws are tightened the blade is in place. 4 N

In operation, the staves are moved past the saws by the carrier consisting of the chains. The plates 3 and 49 forma guide for thestaves, for holding them fiat, and for preventing them lifting. hould a stave of greater thickness or one having irregularitles be placed on the carrier, the 49 will be lifted to permit it to pass. thesaid plates 49 are round as indicated at 62 for the purpose. h'e saws cut the ends of the thus at a single operation equalizing the staves as to length, and putting the roper bevel at each end. When the staves ave passed the saws, they are engaged by the knives, which trim the ends, removing any splinters, or ragged edges that may remain. The said knives are arranged at. the connection of the plates 49 with bars 47 so that the staves are firmly held at this point.

The stavesmove r t e with the disks edges of the saws the form of a shank.55, havbracket 5 on continually one aftc opposite sides an annular ,The tension of the spr1ng 37 adjusted by means of the nuts 38,"so: henitlle' saws 24 are not cutting, thew 7 will barely engage the disks as jus oiiglrto run the saws. Whenever owe, the saws engage the staves the bars are lifted by the and beveled to form a above mentioned by the ar other, and the saws are driven tion disk 17. The pressure. exerted staves may be regulated .by-means o springs 37. j I r y.
